I improved a machine learning classifier used in Amazon’s search engine. I was able to improve the false-positive rate from 55% to 37%. With this, Amazon users can now have access to a more abundant selection of items when buying items.

I collaborated with anther intern to develop 2 PHP user-friendly websites. Through these websites, we helped the company more easily collect foreign users seeking jobs in Japan.

Developed a simulation software for electrodeposition painting technology used in manufacturing cars. Extensively utilized Excel, Hypermesh, Hyperview, EDDL (simulation program that Delight previously developed) to calculate the expected results in each simulation.

I collaborated with another intern to program a car-like robot to autonomously maneuver itself through zig zag corridors without hitting walls and obstacles. We used a sensor to detect walls and obstacles around the car. We found it difficult at first because we did not know how to program in C++. However, with effective collaboration and researching, we were able to teach ourselves C++ language to successfully make the robot move as intended.
